Peritraumatic Somatoform and Psychological Dissociation in Relation to Recall of Childhood Sexual Abuse

Abstract

Objective: Overwhelming experience can evoke psychological dissociation during or immediately after the event, including dissociative amnesia. Whereas some data suggest that such peritraumatic dissociation can also find expression in somatoform symptoms, only a limited range of such symptoms has been systematically studied. The present study hypothesized that peritraumatic psychological and somatoform dissociation are associated with each other, with delayed recall of childhood sexual abuse (CSA), and with CSA severity. Because current somatoform dissociation is most strongly associated with recalled childhood physical abuse (CPA), we also hypothesized that peritraumatic somatoform dissociation is associated with reported CPA over and above CSA.

Method: Thirty-four Dutch women who reported CSA were interviewed using a modified version of the Traumatic Memory Inventory (TMI) which assesses the characteristics of traumatic memories. The participants also completed the Traumatic Experiences Checklist, the Peritraumatic Dissociation Experiences Questionnaire, and the Peritraumatic Somatoform Dissociation Questionnaire.

Results: Peritraumatic psychological and somatoform dissociation were associated with each other, with delayed recall of trauma, and with severity of reported CS A. Reported CPA predicted peritraumatic somatoform dissociation over and above the severity of CS A in terms of the acts involved. Approximately 44% of the women reported independent corroboration of the abuse. Similar proportions of delayed, partial, and continuous CSA memories were corroborated.

Conclusions: This retrospective study suggested that delayed recall of CSA is associated with peritraumatic dissociation and CSA severity. It also suggested that trauma-especially that which involves serious threat to the integrity of the body-may evoke somatoform dissociation. Based on patient report, delayed recall of some CSA memories was as accurate as continuous recall of CSA.
